Please help me. I have been trying to code this from the past 2 years.
I wish to code the Flat real mode by switching to Protected mode and then switch back to the real mode. I want to do this on a P4 1.8GHz Machine with a Intel 845GVSR mother board. I also wish to do this without using the DOS memory managers(Himem.sys or others).
The code made by me halt the machine. Please provide me some alternative to do this. Please I am desparate. Please let me know the code either in C or in Nasm.
